Patented July 7, 1931 UNITED STATES PATENT ERNEST DAVIS, OF SYRACUSE, NEW YORK, ASSIGNOR TO THE PROSPERITY COMPANY INC., OF SYRACUSE, NEW YORK A CORPORATION OF NEW YORK PRESSING MACHINE ELEMENT Application filed April 25,

This invention relates to pressing machines, as garment and laundry presses, and hasfor its object a'particularly simple and efficient construction of one or both of the pressing elements by which a low pressure fluid, as air, can be blown through the pressing face there of and the padding to dry the padding and the work thereon and by which a high pressure fluid, as steam, can be projected through the padding and through the garment pr1- marily to steam the garment without steaming the pad or steaming the pad to a nimmum extent and the garment to a maximum extent.

A further object of the invention is to provide an improved pressing element construction over that shown in my copending application Serial No. 358,139, filed April 25, 1929.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a plan view, partly broken away, with the padding removed, of a pressing machine element embodying one form of this invention.

Figures 2 and 3 are respectively a lengthwise longitudinal sectional view and a transverse sectional view of the pressing element shown in Figure 1.

Figure 4 is an enlarged fragmentary vlew illustrating the relative location of the perforations in the pressing face of the element,

and the jets for the steam,

Figure 5 is a side elevation of a pressing machine embodying this invention.

The machine here illustrated comprises, a head 1 movable toward and'from a buck 2, the latter being supported by a suitable goose neck 3 on a frame 4. The head 1 is carried in the usual manner by a yoke lever 5 pivoted between its ends at 6 to a standard 7 rising from the frame. The head is movable toward and from the buck by any suitable'mechanism either foot operated or power operated, this 1929. Serial No. 358,140.

mechanism being connected to the rear arm of the yoke lever 5.

The mechanism here shown comprises a cylinder 8 having a piston therein, the rod 9 of which is connected to one arm of an angle lever 10 pivoted at its angle at 11 to the base of the frame and the other arm of which is pivoted at 12 to one end of a link 13, the other end of which is pivoted at 14 to the rear arm of the yoke lever. The piston is single acting and the press is opened when the pressure in the cylinder is released by one or more countersprings 15. The flow of motive fluid, as air, to and from the cylinder is controlled by any suitable valve means operated by manuals, as a push button 16 and release lever 17.

The pressing'element or buck 2 is the element of the pressing machine provided with my invention and it comprises a body 18 formed with an internal chamber 19 for a low pressure fluid, as air, the upper wall 20 of this chamber being foraminous or formed with perforations 21 substantially throughout its'area. This wall 20 forms the pressing face of the buck and is usually covered by a padding 22. The wall 20 is here illustrated as detachably secured to the body 18, as by screws 23 extending through the margin of the plate and threading into the margin of the body. A gasket 24 is usually inserted between the margin of the plate and the margin of the body 18.

The chamber 19 is provided with a valve controlled inlet 25 for air, which inletopens through the bottom of the chamber. The body 18 is also preferably formed throughout the greater area thereof with a heating chamber 26 for receiving a heating medium, as steam, from any suitable source.

27 designates conduits for a high pressure fluid, as steam, these being located in the chamber 19 and having comparatively small jet openings 28 arranged in line with the larger perforations 21 and spaced apart from the wall, these jet openings being arranged to discharge the steam jets through some of the perforations 21 and directly through the padding with enough force to penetrate the padding and not spread out through the padding. 7 a

In the illustrated embodiment of my invention, there are three conduits 27 extending lengthwise of the chamber 19 along the middle thereof. These conduits are formed with reversely extending end portions 29 located along the outer sides of the chamber 19, these portions 29 being unprovided with jet openings and being closed at their ends. The jet openings 28 are so fine that water can not readily pass through them so that any condensation is carried along the conduits 27 to the portions 29 where it will be reconverted into steam by the heat from the element. The conduits 27 are connected to a header 30 extending through the bottom of the chamber 19, this header being connected to a feed pipe for comparatively high pressure steam, the pipe having a control valve 31 therein of any well known construction.

32 designates the control valve in the air supply conduit 25. This valve is normally closed, and is opened by a pedal 33 pivoted at 3 1 to the base of the frame and connected to the lower end of a rod 35, the upper end of which is connected to the valve. The pipe is connected toa pipe 36 leading to a suitable source of supply of compressed air, as a blower 36a. The blower is actuated in any suitable manner. The steam valve is operated by a similar pedal lever 37 pivoted on the pivot 3 1 and connected to a rod 38 which operates the valve head within the valve casing 31.

In operation, when the pedal 37 is depressed, steam enters the pipes 27 from the header and jets through some of the perforations 21,. that is, it jets through the perforations 21 with sufficient force to penetrate or pass through the padding and blow and distribute through the garment thereon Without distributing through the padding. By depressing the pedal 33, air of comparatively low pressure passes into the chamber 19 and distributes throughoutthe same and passes through the perforations 21 through the padding and the garment.

This buck construction is particularly advantageous in that it provides a simple and economical way for-projecting high pressure steam through line et openings and the large perforations 21 and through the padding and the work thereon and also a low pressure fluid as air through the same openings 21, it being understood that large openings suitable for air are too large for projecting steam with any force unless the pressure of the steam is very great. It is impractical in a pressing machine to supply steam at a sufficient pressure to pass through a padding with force through large holes adapted for passing air therethrough.

What I claim is:

1. A pressing machine element comprising a body formed with an internal chamber for a fluid and with perforations opening,

from said chamber through its pressing face and a conduit for a fluid under pressure having et openings in said chamber in line with the perforations and spaced from the inner ends of the perforations.

2. A pressing machine element comprising a body formed with an internal chamber for a fluid underlying the pressing face of said element and with perforations opening from the chamber through its pressing face and a conduit for a difierent fluid having jet openings in said chamber spaced from the inner ends of the perforations and located in position to discharge through said perforations, and valve controlled means for supplying the fluid to the chamber and the conduit respectively.

3. A pressing machine element comprising a body formed with an internal air chamber underlying the pressing face of said element and with perforations opening from the chamber through the pressing face of said element, a conduit for steam having jet open ings in said chamber alined with and spaced from the inner ends of the perforations to discharge steam through said perforations and valve controlled means for supplying air under pressure to said chamber and steam to said conduit.
